Will painting the interior doors black help?

Grays are tricky ... I assume repainting is not an option?

Furnishings,artwork, decor and rugs could help and black could possibly help. What is the paint color? A few other perspectives of your space would help.

Sometimes a change in the lighting can help affect how the colors read. But really, this is why people suggest trying samples of the colors on a few walls in your house, so you see how they look in your context and light conditions. Nothing is predictable.

you really need to place your furniture in there. then we can see how it works.

A good tip I give to clients, if they are still unsure after a color consultation, paint a foam board (like poster board, but is more sturdy, just have to paint both sides of the board or it will bow as paint is drying) with 2 coats of the wall color you are thinking of. By doing this you can walk or prop the board at any section of the room. This will clearly show you how the color reacts to natural and artificial light. Color is highly affected by natural and artificial light. As you walk around the room with the board you will see how the color changes; darker in corners, etc. Also, when selecting color look at the color in the room vertically as it will be on your wall on a clear day. Put a white paper behind the color swatch if the wall surface you will be painting is a different color than white so it isn't influencing the color swatch. Most people don't realize how difficult it can be to get the right tone. It's not easy. If a hint of an unwanted undertone shows on a little swatch, you can bet it will be more obvious in a larger "swatch" being your walls.

On my computer screen, only the bottom portion of your walls reads bluish, and I see other color bands moving up the wall. Perhaps the blue is a result of the light reflecting off your floors and, as others have hinted, furniture and rug placement might alleviate that? I painted my kitchen a light ivory, and didn't take into account that all the backyard trees and grass would bounce green onto my walls.

Congrats on the new house!

I have grey screen on my bedroom walls and it looks blue, particularly when matched with orange or blue. That cocoa brown or taupe is a good contrast color. I think you will just have to downplay it and live with a slightly different vibe than your inspiration photo. Why are there blue marks on the floor? I think lighting may help with the reading of the color, but you've got a grey that is neutral but will skew blue but it doesn't have to be overwhelmingly blue if you deal with maybe the lighting and accents. I think once your floors are stained more BROWN and dark, not so grey, it will look better. Grey screen is a gorgeous color so I think just keep going with your inspiration and the room will look great. Or repaint now while you have the chance.

Like the others, I'd wait until the flooring is finished AND the lighting is in to judge. Grays are tricky. My bathroom walls have six coats of paint on them because I didn't understand that.

FWIW, the color you picked has a blue undertone and your inspiration photo has a green one. If you're wanting something that doesn't read blue or cold next time I'd find one with a green undertone (or red, but that wasn't your inspiration pic.)

I'm not sure how to add other colors to make it appear less blue. I would find things you like (art) to pull things together. I think any type of complimentary colors will only enhance the blue. Does the color feel cold to you or do you just not care for how blue it looks?

When I googled images of your sw gray screen, I noticed that the ones showing a dark floor looked less blue and more gray. Hopefully the dark flooring will work for you.

I would not select your furniture and other decor based around a paint color you don't even like. The cheapest solution is to repaint, and you'll be happier long term. You will always see the blue undertone on your walls.

Your inspiration picture looks very similar to the paint color I used in my own house which is SW Mindful Gray. In my house, Mindful Gray looks Gray with a slight green undertone which visually looks like Gray with the faintest hint of brown, thus appearing warm Gray. I don't know what the actual undertone of it is, just that in my own house it looks to have a green undertone. Gray Screen looked very blue in my house and I knew I needed a warm gray (but still light). I would look at some warmer grays, get samples, then paint a poster board or paint directly on the walls in at least a 2x2 square.

What color is your ceiling? It looks dark? Perhaps a cooler white on the ceiling might help? Just not ever going to really get rid of the blue undertones no matter what. It is emblazoned on your eyeballs! Light furniture and good LED lighting will help but might also draw out more blue if you don't get cool LEDs. Good luck.

I would get the furniture you really like and ignore the wall color. Same with carpeting and drapes. Once everything is in place, go to town with large pieces of art and gallery walls. The visual impact of your walls will be greatly lessened when the focus is on your furniture and art. Also, experiment with lighting to see which type warms up the wall color. The color you have is actually quite nice, and I'm not a fan of cool blues and grays. I hope you realize, by the way, that a dark wood floor is very unforgiving in that it shows the slightest bit of dust or fluff. To me it also looks rather forbidding and unfriendly, especially when it's highly polished.

Here is SW Mindful Gray in my home:

Gray Screen belongs to the blue-green hue family. Specifically, it lives in the blue-green hue family over towards the blue hue family. It has a notation of 6.40 BG which tells us that Gray Screen is closer to blue than it is to green and that's how we know to expect blue overtones.

There's nothing hidden or under anything. No visual gymnastics required when you have a color notation.

It looks blueish because that's exactly what it is - what you're seeing, what has happened with the color in your space has absolutely nothing to do with undertones. The fact that it does look blueish in your space means you have a relatively balanced quality of light to work with. Which is a good thing.

What colors can i incorporate to make the walls appear less blue?

Any color from the same hue family neighborhood will make the wall color look less blue and more gray. Especially colors that have more chroma, are more colorful, have more saturation than Gray Screen.

Any color from any other hue family will make Gray Screen look more blue. The farther away the hue family is from 6.40 blue-green, the more it will intensify the blueness. For example, you don't want to use red.

To get the color you were going for, you'd have to look at near neutral grays that belong to the yellow/green-yellow hue family neighborhood.
